tion of" the slots in the ends of bar 6 is I The improvements. set forthherein relate specifically to the figurehead described n United StatesPatent Number 1,511,044,.1ssued October 71., 1924, to Roy W. Adams. Thiscertain type of figurehead is a representation of a winged figure andhas movable. wings. I

In the accompanying drawings: I

Figures 1, 2, and 3 show top, front and side views respectively of amechanism that tilts the wings of the figurehead in such a way that theupper and under surfaces of the wings would receive the pressure of acurrent of air alternately, should the current of air be coming from thedirection in which the figurehead is pointing. Receiving the presure ofa current of air on the upper and under surfaces alternately causes thewings to move up and down, or flap, in imitation of the efforts of aflying creature. Figure 2 shows the front view of the mechanism inposition within the hollow body of the figv urehead, shown in section,and the front elevation of the wing joints, wing arms and part of thewings.

In Figures 1, 2, and 3, 1 is a plate having a slot- 2 and a closedgroove 3. 21 is another plate having a slot to match the slot inplate 1. Plates 1 and 21 areheld together by screws with spacers 13between them. 6 is a bar extending through the slots in plates 1 and 21.4 is a crank, located between plates 1 and 21, connected to bar 6, andhaving a. pin 5 which is slidable in groove 3. 15 is a spring held inposition by a clip 18 and two spacers or washers 16 and 17 which arefastened to one of the plates. The ends of spring 15 are curled to forman eye at each end as shown in Figures 1 and 3. 26 is a pin whichextendsthrough an arm of crank 4. Pin 26 is so positioned that it mayengage the eye in either end of spring 15 causing crank 4 to becomeoperatively connected to either end of spring 15. As crank 4 is drivenup and down, by the wingarms acting through bar 6, spring 15 is broughtunder torsion by the arm of crank 4 acting alternately on its two ends.The action of spring 15 causes the pin 5to follow around groove 3 ascrank 4 is moved up and down. As pin 5 follows around groove 3 crank 4imparts a turning movement to bar 6. In each end of bar 6 is a slot bywhich each end is operatively connected through a yoke to one of thewing arms 14. As bar 6 is turned the inclinachanged and this change ofinclination is imparted to: the wings 8, through the wing arms 14..

The action described herein is. identical with the action dcscribedinthe specification of United States Patent Number 1,511,044, thedifference in the mechanisms being: The mechanism herein described has asingle crank operating between two plates instead of a single platewith. a crank on either side and: The mechanism herein described has atorsion spring acting upon an arm of the crank in place of the tensionsprings used in the mechanism of Patent Number 1,511,044. The torsionspring makes for a smoother and simpler acting mechanism.

In the accompanying drawings Figures 4 and 5 show a top and front viewof a type of wing joint used in the figurehead. In Figures 4 and 5, 19is a cylinder which operates in a sleeve 20; 14 is a wing support memberor wing arm which extends laterally through cylinder 19 and sleeve 20.To one end of 14 is fastened the wing 8, the other end is forked with apin 9 across the end of the fork forming a yoke. Pin9 operates in a slotin the end of bar6 as shown in Figure 3. Sleeve 20 is cut away on eitherside so as to permit angular motion of the of the wings requires thatwing arm 14 be v able to rotate.

Figures 6 and 7 illustrate anothertype of wing joint. In Figures 6 and 7wing arm 14 extends through a spherical member or ball 22 "which issupported between two members 23 and 24, which in turn are set in thebody 12. Members 23 and 24 are so shaped as to form a socket-likesupport for ball 22 as shown in Figure 7. Wing arm 14 may be free torotate in ball 22, or the two members may be made integral since ball 22may rotate in its socket. Ball 22 operating in a socket makes itpossible for wing arm 14 to execute an angular movement as well asrotate.

I claim:

1. A representation of a Winged figure i having a hollow body, movableWings and support members therefor rotatably mounted in said body,plates located Within said body, each of said plates having a slot andeither of said plates having a closed groove, a bar extending throughsaid slots and having its ends operatively connected to said supportmembers, a crank connected to said bar, said crank having a pin slidablein said groove, a double acting spring operatively connected to saidcrank in such a Way-as to cause said pin to follow around said groove inresponse to Wind pressure upon said Wings.

2. In a device of the kind described the combination of a member havinga cylindrical shaped cavity, a cylindrical member operating Within saidcavity, athird'memlar motion, a bar connected to one end of 25 saidthird member for imparting rotatory motion thereto and receiving lateralmotion therefrom, and a representation of a Wing of a Winged creaturemounted on the other end of said third member.

ROY W. ADAMS.
